Cannot generate correctly when module name contains subdirectory path

### Affected version

3.4.0

### Bug description

For example, I have an archetype like this:

```
|- __rootArtifactId__-openapi
|- api
| - index.ts
```

When generating the `index.ts` file, the path will be replaced with `__rootArtifactId__-open/api/index.ts`.
